Wine is a personal thing, what some people love, others hate. So you have to go through and find ones you like at a price you are willing to pay.

There are various lists out there of best wines under some amount of money, here's one for Cabs under ten bucks

and another for under $15

The only way you are going to find something you like is to try a bunch of stuff, much of which you probably won't like. Like any wine in any price range, there is such a huge range that there is nothing everybody will like.
